Jack's a patient individual - I alerted him to this set when it first came up on Fleabay back in October.
But the price was a bit over the top then, as I recall.

Not sure about Hickok, but
Stokes are badge manufacturers, rather than jewellers.
Still very much in business, too -
http://www.stokesbadges.com.au/index.phpI probably have a bigger collection of metal badges than most people, and some of them were made by Stokes.
I was very much into going to motorcycle rallies for 20 or so years, and it's usual for a commemorative badge to be made and sold to attendees at these events.
